NAMT Fremework for Discrete Parts Manufacturing: Industrial Review Roundtable

August 1, 1996
Author(s)
Neil Christopher, Selden Stewart
As a result of the review, we have focused and clarified the objectives of the Framework project as follows:analysis of specifications for relationships to existing standards and specifications and for internal consistency, testing and validation of

Real-Time Single-workstation Obstacle Avoidance Using Only Wide-Field Flow Divergence

August 1, 1996
Author(s)
Theodore(Ted) Camus, David Coombs, Martin Herman, Tsai Hong Hong
A real-time robot vision system is described which uses only the divergence of the optical flow field for both steering control and collision detection. The robot has wandered about the lab at 20 cm/s for as long as 26 minutes without collision. The entire

Stitching of Equatorial Profiles for Extended Spatial Range Assessment

August 1, 1996
Author(s)
P Sullivan, R E. Parks, Lianzhen Shao
This paper describes a method for stitching multiple overlapping interferometric measurements of the equator of a high quality sphere to produce a single profile representing the roundness of the ball. The resulting optical profile measurement is compared

Comparison of Submicron Particle Analysis by Auger Electron Spectroscopy, Time-of-Flight Secondary Ion Mass Spectrometry, and Secondary Electron Microscopy With Energy Dispersive X-Ray Spectroscopy.

July 31, 1996
Author(s)
George W. Mulholland, K D. Childs, D Narum, L A. LaVanier, P M. Lindley, B W. Schueler, A C. Diebold
Particulate contamination can result in a significant yield loss during semiconductor device fabrication. As device design rule dimensions decrease the critical defect size also decreases, resulting in the need to analyze smaller defects. Current

Chemical Effects of CF3H in Extinguishing Counterflow CO/Air/H2 Diffusion Flames

July 28, 1996
Author(s)
G. S. Fallon, H K. Chelliah, Gregory T. Linteris
The relative importance of introducing CF3H as a fire suppressant with the oxidizer or the fuel stream, and its chemical and thermal effects on the extinction condition of counterflow CO/air/H2 diffusion flames, are investigated both experimentally and

Chemical Effects of CF3H in Extinguishing Counterflow CO/Air/H2 Diffusion Flames.

The relative importance of introducing CF3H as a fire suppressant with the oxidizer or the fuel stream, and its chemical and thermal effects on the extinction condition of counterflow CO/air/H2 diffusion flames, are investigated both experimentally and

Effect of Halogenated Flame Inhibitors on C1-C2 Organic Flames

July 28, 1996
Author(s)
T Noto, Valeri I. Babushok, Donald R. Burgess Jr., Anthony P. Hamins, Wing Tsang, A W. Miziolek
The influence of CF3Br, CF3I, CF4, CHF3, C2F6, and C2HF on laminar flame propagation in mixtures of CH4, CH3OH, C2H6, and C2H4 with air has been determined by numerical simulaitons. Comparisons are made with experimental results and earlier calculations

Global Properties of Gaseous Pool Fires

July 28, 1996
Author(s)
Anthony P. Hamins, K Konishi, Robert P. Borthwick, Takashi Kashiwagi
Global flame properties were measured as a function of fuel mass in a series of experiments conducted on gaseous pool fires burning in a quiescent environment. The measurements included radiative heat loss, heat transfer to the burner, and sensible
